The Hanna Instruments HI 101 is a submersible pH electrode with a double polytetrafluoroethylene (PTFE) junction, polyvinyl chloride (PVC) body, flat tip, double O-ring seals, HI 101/3 adapter, 3m (9.8') cable, a Bayonet Neill-Concelman (BNC) connector, and operates in pressurized systems. A pH electrode is commonly attached to a pH meter to measure the pH of a substance such as water, food, beer, or wine in lab, industrial, and food applications. This electrode has a PTFE junction that reduces sample solution ingress into the reference compartment for longer electrode life. The flat tip eliminates deposits that can foul the electrode and is sealed O-rings for immersion in liquids. The electrode operates in pressurized systems up to 87 psi (6 bar). A female BNC connector provides tight cable connections. The electrode comes with the HI 101/3 adapter and a 3m (9.8') cable.SpecificationspH range0 to 13JunctionDouble PTFEElectrolytePolymerReferenceDouble, Ag/AgClBody materialPVCTip shapeFlatOperating temperature20 to 40 degrees C (68 to 104 degrees F)Maximum pressure87 psi (6 bar)ConnectorBNC femaleCable3m (9.8')An electrode, also called a sensor or probe, is an instrument used with a meter to test and measure parameters of a substance. All electrodes are probes or sensors, but not all probes are electrodes or sensors. Probes, such as temperature probes, are used to penetrate a material for measurement. Common electrode types are pH, total dissolved solid (TDS), and ion selective electrode (ISE). Electrodes can be half-cell or full-cell (also called combination) types. They can be refillable or non-refillable. Housing material is typically glass or epoxy, and sensors are commonly made with stainless steel or a glass bulb. pH electrodes, which measure the pH of a substance, often have a glass bulb. The bulb senses hydrogen ions, and generates a millivoltage that is picked up by the filling solution and transferred to a wire that connects to the pH meter. Ion selective electrodes (ISEs) respond selectively to ions in ...

The Milwaukee combination electrode has a double-junction reference to protect against silver wire contamination and to help prevent clogging when testing dirty water and solutions with heavy metals or organics. This combination electrode contains both the measuring half-cell and the reference half-cell to minimize electrostatic interference and provide consistent readings. Its epoxy body is impact resistant, durable, and sealed and filled with an electrolyte solution gel for minimal maintenance. It is available in both pH and ORP models. The pH model has a measurement range of 0.00 to 14.00 pH. The oxidation reduction potential (ORP) model has a platinum sensor for measuring dissolved oxygen in aqueous solutions and a measurement range of +/-2,000 mV. It withstands temperatures from 0 to 70 degrees C (32 to 158 degrees F). The electrode is 12mm in diameter and 120mm long, and has a 1m cable with a Bayonet Neill-Concelman (BNC) connector for attaching to meters with a BNC connection. pH electrodes measure the acidity or alkalinity of a substance. ORP electrodes, also known as redox electrode, measure the ability of aqueous solutions to act as oxidizing or reducing agents. Both pH and ORP electrodes are commonly used by researchers, manufacturers, and hobbyists in hydroponics, aquaculture, agriculture, and winemaking, among other applications. An electrode, also called a sensor or probe, is an instrument used with a meter to test and measure parameters of a substance.
